For design of composite concrete members, the behavior between two materials; concrete and steel is considered significantly. And shear studs are generally used for effective composite action. The purpose of this paper are to propose an equation of strength of shear stud embedded in high strength concrete, and to evaluate the validity by comparing with the current design codes and existing proposed equations. The equation was proposed by regression analysis based on the test results of steel pipe encased composite members manufactured by considering diameter of shear stud and ratio of diameter to height of shear stud as variables. The comparisons of the test results with the design codes and existing proposed equations showed that KBC2009 and the equation of Cheong et al. have big error; 48.78% and 28.03%. And the equation proposed in this paper indicate relatively smaller error of 3.69%. It indicated that the proposed equation has higher accuracy for calculating the strength of shear stud embedded in high strength concrete. |
